4 Claims. (01. 229-17) This invention relates to improvements in cartons and more particularly to the type of car-- Another object of the invention is the method of folding the end flaps of the carton with which my pouring spout is associated, in such a manper that the cart ton, and particularly the pouring spout, is maintained in a sealed relation to the carton; not only for delivery to the user, but also during subsequent use of the carton with the pouring spout in closed position.

' Another object of the invention is the provision of a guideway for one wall of the pouring spout for guiding the same into its sealed relation with the wall of the carton and also to stabilize:

the spout throughout its range of operation. These and other objects willappear as my invention is more fully hereinafter described in the following specification, illustrated in the accompanying drawings, and finally pointed out in the appended claims. In the drawings:

Figure 1 is apian view of carton material scoredcut and perforated in accordance with my invention. Figure 2 is a perspective end elevation of the carton showing the end flaps thereofrin open 1 position and'the pouring spout itself in opera-.- tive engagement with one of the-side walls of the carton. 1 Figure 3 is an' end elevation somewhat similar to Figure 2 but showing more particularly the details of construction of the carton.

Figure 4 is an end elevation of the cartonin its completely 'folded and sealed form;

5 Referring now more particularly to the drawjugs;

Referenc numeral I indicates, generally, carton mate a1 properly cut and scored in accordance with my invention; and in readiness to be folded into'a carton. The material is formed in to side wall panels 2 and 3, and end wall panels 4 and if. Integral with these wall panels are end flaps 6, 1,8,9, III, II, l2 and i3. Formed integral with the end wall panel 4, is an auxiliary 55 end wall panel ll, withinwhich 1 form a depression I5, ,to /be hereinafter more fully described. I All of the said panels are divided by fold lines A, B, C, D, E and F, and all are folded around these division lines as will be hereinafter more 5 fully pointed out.

In large operations where my cartons are to be produced in large quantities, I provide the usual die-cutting machine with an augiliary cutter which is designed to cut out the irregular 1o portions of the various panels as shown in Figiire 1, simultaneously with the cutting operation that forms the blank carton materi The end flap III, has one of its corners out out to form one wall of a pouring spout, indi- 15 cated, generally, at It, which-consists of two integral walls I1 and Hi. The wall I8 is formed at its outermost end with a projection l9, adapted for engagement with the underside of panel l3 when in folded position, act as a limit stop 20 'thereagainst and to preventb er-opening of the spout. The edge of the panel l4 adjacent the wall 18 of the spout, as shown in Figure 1, is beveled as at 20, to act as a guide for the wall l8, and to facilitate its entering a space or cav- 25 it'y formed by the depression l5, between certain of the walls, as will be more fully hereinafter described. a

Within the end flap I3, I define, by a perforated line 2|, a'portion 22, which is adapted to be so the opening operation. This portion 22, is formed with a projection 23, which is defined by a per- 35 -forated' line 24, within the side wall panel, I. The projection 23, forms a lifting tab, and for the convenience of the user, I relieve the end of the tab as at 25, for the insertion ofa fingernail or the like for disengaging the tab and the 40 portion 22, from its'related panels in the initial opening of the spout. After such opening, the portion 22, remains permanently secured to the wall lab: the spout.

The folding operation of the material shown in Figure 1 to form my new and improved carton is as follows: 5 Y

Assuming-that the blank material is resting on a table, the end panel 5 is held against the table .while the side walls 2 and 3 are drawn upwardvertical position around the folding lines in the panel ll will form a cavity or slot between the inside surface of the panel 8 and the inside surface of the auxiliary panel l4. At this point in the folding operation,'the wall ll, of the spout I6, is folded around-the fold line 0, into a position at right angles to the wall l1. When the wall l8, of the spout is in this position, it is thenin alignment with the cavity heretofore described, and indicated at 26 in Figure 3. When in this position, the pouring spout is free to be moved around the fold line B,-into a closed or open position. When the spout is being moved into a closed position, the wall I8, of course, will advance into the cavity 26 and be guided and stabilized thereby. With the side and end walls thus folded together, the end flaps are ready to be folded and sealed in the following manner:

The end flaps I and 8 are folded inwardly around their fold lines A and then the end flaps 8 and 8 are folded over onto themselves into an over-lapping position and sealed by any approved means, such for instance, as glue or the like. The carton is then brought up into a vertical position to rest upon the sealed end thus formed.

With the carton in a vertical position, the pouring end is now ready to be folded in substantially the following manner: The wall l8, of the pouring spout 'isnrst introduced into the cavity 26, and moved downwardly therein until the fold line C, rests squarely along the beveled edge of the auxiliary panel ll. Then the end panels l0 and I2, are folliedinwardly. Following this, the

panel II, is folded downwardly against the two inwardly turned endpanels l0 and I2. The radius oi the cut-out-portion of the panel II, is greater than the radius of the cut-out portion of the panel Hi, from which the wall ll, of the pouring spout was formed. Consequently, when the flap ll, overlaps the flap M, a shelf 21, is formed to support the curvilinear edge of the wall H, of

the spout. Following this, the inside surface of the flap I3, is glued or otherwise pasted, and is then folded downwardly against the assembled end panels just described. With the 'flap i3 thus in place, it is obvious that that end of the carton is completely sealed. The lifting tab 23 will then appear in the side wall 3.

In opening the carton after the 1mm; tab has been broken away, around its perforated line 24,

a further upward pull exerted upon the tab will cause the portion 22, which now adheres to the wall ll, of the spout, to move thereafter with the pouring spout. From the foregoing, it is obvious that the carton formed in accordance with my in- .vention, is made'sift-proof or lead-proof, not only immediately'after its initial filling and sealing,

but also during all subsequent use, by the comwall 4, of the carton, when the two are brought together.

Whilev I have shown a particular form of embodiment of myinvention, I am aware that many minor changes therein will readily suggest themselves toothers skilled in the art without departing from the spirit and scope of my invention.

Having thus described the invention, what I claim as new and desire to protect by Letters Patent, is:

1. A carton comprising side and end walls and overlapping and sealed end flaps, a pouring spout formed integral with oneof said end walls and movable with respect thereto, said pouring spout having two walls, a guideway formed between overlapping portions of said side and end walls and adapted to slidably embrace one wall of saidpouring spout. I t

2. A carton having four side and'end-walls and overlapping end flaps, an auxiliary wall formed integral with one of said end walls and adapted when folded to overlie one of said side walls, a depression formed in said'auxiliary wall to form a pouring spout formed integral with one of said end walls and movable with respect thereto along one edge of one of said walls of the pouring spout, the other of said walls adapted to be moved within said depression.

' 3. A carton having four side and end walls and overlapping -end flaps, an auxiliary wall formed integral with one of said end flaps and adapted when folded to overlie one of said side walls, a depression formed in said auxiliary wall to form a space between itself and said abutting side wall, a pouring spout formed integral with one of said end walls and movable with respect thereto along one edge of one of said side walls of the pouring spout, the other of said walls adapted to be moved within said depression, and

having two walls one of which is formed integral with said first mentioned and wall and the lower edge of its opposite wall fying immediately above said bevelededge, said depression forming a guideway when said auxiliary end wall is united with one of said side walls.
